VALVE.

Specification of Letters Patent.

Patented Mar. 17, 1914.

Application filed November 27, 1912. Serial No. 733,907.

To all whom it may concern:

Be it known that I, WILLIAM G. Esrnr, a citizen of the United States, residing at Duquesne, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Valve, of which the following is a specification.

The present invention relates to improvements in valves, the primary object of this invention being the provision of a novel form of spring closed valve, which is especially adapted to be used in connection with flush tanks.

, A further object of the present invention is the provision of a novel form of valve adapted to be connected to the outflow of a pipe, the same being normally held closed to be operated to permit the proper flow of water through the valve, such flow being regulated so as to be steady and not intermittent, the same forming in reality a pressure reducing medium so that the flow of water under high pressure will be reduced to. a gradual flow,

WVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described. and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a sectional view through a low hopper flush tank with the present invention in operable relation thereto. Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is a vertical central sectional view through the complete valve casing and valve with the parts in normally closed position. Fig. 4c is a sectional view illustrating a means whereby the valve may be seated by water pressure and the spring may be dispensed with.

Referring to the drawings, the numeral 1 designates the outer casing of a flushtank hopper, while 2 designates the inner metal and water containing tank, both of which are of usual construction. Led into the tank 2 is the supply pipe 3, while led thereaway from is the flushing conduit A, the same being controlled by a buoyant ball valve 5 which iselevated through the medium of the operating lever 6, mounted in the upper end oi the ournalingpost 7. A rod 8 is connected to the opposite free end of the lever 6 and is operable eXteriorly of the casing 1 through the means of the push button 9. Pivoted to the end of the lever adjacent the rod 8 1s a depending rod 10 whose button 11 limits the upward movement of the free end of the valve actuating lever 12, the detailed structure of which will presently appear.

The coupling member 13 of the valve structure is provided and is connected by any well known means to the outlet end of the water supply conduit 3, the lower end 13 being provided with the chamber M which is sealed by the removable valve seat 15, which has seated thereupon the valve 16, whose spring 17 is of such a tension as to offer suflicient resistance to the inflow of water to reduce the pressure so that the objectionable outflow of water into the tank 2 will be removed and a steady constant flow permitted thereinto. The spring 17 will be made of varying strength in order to operate the valve 16 according to the pressure supplied through the conduit or pipe 3. A channel 18 is formed through the base member 13 and enters the chamber 19 of the removable casing 20 which has its lower end detachably connected to the threaded boss 21 of the member 13. An outlet port 22 is formed concentrically in the upper end of the chamber 19 and leads through the duct 23 into the downwardly projecting outlet 24, said outlet 24 being so positioned as to normally project the water below the level of the water within the tank 2, thus decreasing the noise, due to the inrush of water within the tank 2, to a minimum.

Formed integral with the threaded boss 21 and projecting upwardly and within the casing 20 is a stem 25 provided with the cupped member 26, and also the socket 27 said socket 27 being in axial alinement with the bore 28 formed in the upper end of the casing 20 and constituting therewith a guide for the valve stem 29 which is permitted a vertical sliding movement. On this valve stem 29, as clearly shown, is carried the metal guiding disk 30 and the valve gasket 31 which is normally held by the spring 32 upwardly to close the port 22 and thus prevent the inrush of water from the casing or chamber 19 through the outlet port 2 1.

The operating lever 12 is journaled between the apertured lugs 33 formed integral with the casing 20 and has its integral plunger depressing lug 3 1 disposed to abut the upper end of the valve stem 29, so that when the push button 9 is depressed, the rod 10 will also be depressed and consequently depress the lever 12 to move the valve 31 from the valve seat 22 and thus permit the inrush of water through the port 23 into the outlet spout 2 1 of the casing 20.

In order to provide a means for permitting the automatic elevation of: the operating lever 12 to release the stem 29 to the action of the spring 32 after a predetermined amount of water has entered the tank 2, a lug 35 is formed integral with the lever 12 and has journaled between it and the projecting portion 01" the lug 34:, a pin 36. J ournalod within the apertured lugs 37 formed integral with the casing 20 is the float actuated lever 38 whose enlarged lower end is provided with a slot having the reduced end 40 and the enlarged end 41, this peculiar shaped slot embracing the pin 36 of the lever 12 so that when the float 43 connected to the lever 38 by means of the rod 42, is in lowermost position, the pin 36 will be seated within the portion 10 of the slot and the lever 12 will be locked in its lowermost position to retain the valve 30 depressed against the spring 32 and permitting the inrush of water into the tank 2. As soon as the water has reached a sufficient level to elevate the float 13, it is evident that the lever 38 will also be elevated so that the portion 11 above the portion 410 of the slot at the lower end of the lever 38, will permit the spring 32 to elevate the stem 29 and cause the pin 36 to seat within the enlarged portion 11 of the slot, thus automatically closing the valve, and only after the necessary amount of water has been permitted to enter the tank 2.

The spring 32 is used primarily to assist in moving the valve 31 toward the seat 22, the pressure fully seating the valve, and should it be desired the cup 26 may be perforated near its lower end as at 50 and the spring 32 dispensed with. By this means the pressure will enter the cup below the plunger 30 to seat the valve 31. This structure is illustrated in Fig. 4:. In this form of valve, the pressure of the water at the outlet is reduced to relieve the same of the undesirable action where high pressure is used.
